Rossiters have over 20
years experience in diesel tuning. We were the first company to
launch the plug in style turbo diesel tuning system in the UK in the
mid 90's. Others then jumped on the band wagon, but none have the
same years of experience of this type of tuning. We are now UK
distributors for AC Schnitzer diesel tuning for BMWs, and dealers
for Steinbauer tuning which is available for almost every modern
diesel vehicle, including cars, light and heavy commercials and
agricultural machinery. Both AC Schnitzer and Steinbauer offer
astonishing improvements in both performance and economy, with the
great backup and depth of experience you can only get at Rossiters.

AC
Schnitzer

AC
Schnitzer is the premium diesel tuning solution for BMW and
MINI. Combined with extraordinary research and
development carried out at the Nürburgring, AC Schnitzer are
the only tuning company offer a 2 year warranty on the
engine and drivetrain, to run concurrently with the
manufacturer's warranty. In other words, if there is a
problem with the tuned engine and the manufacturer decides
not to cover it under warranty, AC Schnitzer will step in
and make the repairs. This situation is incredibly rare, but
the AC Schnitzer warranty allows you to fully enjoy your
tuned engine with complete peace of mind.

A 20% increase in power is
typical and, in some cases, a slight improvement in fuel
consumption is possible.

Prices start at around £2000
+ fitting.

Steinbauer

Steinbauer diesel tuning is the cost-effective but high
performance solution for all modern diesel (and some petrol)
turbo engines. Unlike some of the cheaper engine tuning
"boxes" available elsewhere, which simply increase fuel
pressure to produce power gains, Steinbauer is a
well-researched and developed system that integrates with
your vehicle's electronics perfectly. This level of control
prevents unwanted side effects such as engine management
lights, black smoke or excessive fuel consumption from
over-fuelling.

As with AC Schnitzer a 20%
increase in power is typical and a slight increase in MPG is
possible.
